The working principle is as follows: when in use, sewage with purification enters the sewage mixing component 1 along the sewage input pipe 16 to be mixed with the flocculating agent put into the feeding component 2, and then the mixed sewage enters the filtering component 3 to be filtered and separated;

when feeding, a flocculating agent is fed from the opening at the top of the discharging groove 22 at the top of the main body 21, the rotating roller 25 is rotated along with the starting of the driving motor, when the discharging groove 26 on the rotating roller 25 is positioned at the top of the rotating roller 25 and communicated with the discharging groove 22, the flocculating agent in the discharging groove 22 enters the discharging groove 26, then the flocculating agent downwards along with the rotation of the rotating roller 25, and when the discharging groove 26 is communicated with the third butt joint pipe 24, the flocculating agent in the discharging groove 26 enters the sewage mixing component 1 along the third butt joint pipe 24;

when the flocculating agent enters the mixing pipe 13 along the third butt joint pipe 24, the first motor on the mixing box 11 is started, the first motor drives the first rotating shaft to rotate, then the mixing pipe 13 rotates, when the mixing pipe 13 rotates, the fan blades 19 above the partition plate 12 rotate along with the first motor, the fan blades convey the air outside the mixing box 11 to the inside of the mixing box 11 along the air holes in the top of the mixing box 11, then the air enters the inside of the mixing pipe 13 along the air inlet holes 101 in the mixing pipe 13, then the air flow entering the mixing pipe 13 pushes the flocculating agent downwards to the bottom opening of the mixing pipe 13, then the flocculating agent is discharged from the bottom of the mixing pipe 13 to be mixed with the sewage in the mixing box 11, meanwhile, the stirring rod 18 at the bottom of the partition plate 12 rotates along the mixing pipe 13 to stir the sewage, the stirred sewage moves upwards layer by layer along the circulation holes 15 in the diversion plate 14, and finally is discharged from the first connecting pipe 17 to the filtering component 3 for filtering, in the process, the sewage moves upwards layer by layer, so that the sewage can be fully mixed with the flocculating agent, and meanwhile, the sewage can be aerated by air on the mixing pipe 13 during mixing to intensify the flow of the sewage, so that the sewage and the flocculating agent can be fully mixed;

during filtering, sewage enters the first butt joint pipe 311 along the first connecting pipe 17, then the first butt joint pipe 311 is discharged downwards to the filtering unit 33 on one side of the partition plate 32 for filtering, during filtering, the sewage flows downwards to the first filtering plate 61 and the second filtering plate 62, a flocculation part in the sewage is filtered and is positioned above the first filtering plate 61 and the second filtering plate 62, then the second motor which drives the sleeve 45 to rotate is started, the sleeve 45 drives the rotating disc 41 fixedly connected with the sleeve 45 to rotate, the rotating disc 41 drives the first push rod 43 and the first scraper 44 which are positioned on the rotating disc 41 to rotate, when the first push rod 43 on the rotating disc 41 is positioned below the axis of the rotating disc 41, the sliding groove 42 is communicated with a cavity at the bottom of the extension plate 48, at the moment, an air inlet pipe at the bottom of the extension plate 48 conveys air in the isolation sleeve 46 to the inside of the sliding groove 42, so as to push the first push rod 43 downwards, at the moment, the first scraper 44 moves downwards to contact with the top of the first filter plate 61, the first scraper 44 scrapes off dregs on the first filter plate 61 towards the second filter plate 62 along with the anticlockwise rotation of the turntable 41, and meanwhile, the dregs are pushed to the top of the guide plate 63 from the top of the second filter plate 62, then the second scraper 54 on the pushing unit 36 pushes the dregs downwards to the upper right of the solid-liquid separation plate 37 along the guide plate 63, and at the moment, the solid-liquid distribution plate 37 separates sewage and flocculated dregs;

when the first push rod 43 on the turntable 41 is located above the axis of the turntable 41, the sliding groove 42 is communicated with the cavity at the top of the extension plate 48, at this time, the gas in the cavity at the top of the partition plate 47 is pumped outwards by the gas pumping pipe at the top of the extension plate 48, at this time, the gas in the sliding groove 42 is pumped out by the gas pumping pipe, so that the first push rod 43 moves upwards, the first scraper 44 moves towards the direction of the turntable 41, and in order to avoid collision between the first scraper 44 and the pushing unit 36, the partition plate 47 is obliquely arranged;

the sewage after the preliminary filtration is conveyed to the interior of the discharge pipe 39 along the return pipe 38, the sewage is continuously condensed in the interior of the discharge pipe 39, then the sewage is conveyed to the filtering unit 33 on the other side of the partition plate 32 along the second butt joint pipe 310 to be continuously filtered, and then the solid-liquid separation is carried out according to the filtering mode;

this design can the quantitative control quantity of flocculating agent, makes sewage and flocculating agent intensive mixing simultaneously, makes sewage fully flocculate, later carries out the operation of separation flocculation many times to sewage, makes things convenient for sewage and flocculation solid to separate, avoids the filter to block up, improves filter effect and quality, makes sewage fully obtain simultaneously and handles, improves sewage treatment effect.
